IMPROVEMENT IN GRAIN-CLEANERS.

Specification forming part of Letters Patent No. 133,041, dated November 12, 1872.

Mature and Objects of the Invention.

This invention relates to a simplev and portable machine or mill for elleetually cleaning wheat or other grain and separating cheat or other refuse grain therefrom.

Description 0f the Accompanying Dra-wing.'

Figure lis a side elevation of my separator. Fig. 2 is a horizontal section in the line X X. Fig. 3 is a vertical section in the line Y Y.

The inclosing ease or shell consists of a drum or wind-box, A, from one side of which projects tangentially a spout, B, open at both ends. The drum A is traversed axially by a shaft, O, armed with beaters D, constituting a fan, and this fan is rotated by a crank, E, jonrnaled in frame F, and Whose shaft G has a bevel-Wheel, H, that gears with a bevelpinion, I, upon the upper end of shaft O. A hopper, J, on the top of spout B admits the uncleanedv grain through orifice K into a screen, L, suspended by links M M', and subjected to a violent shaking motion by tabs N, that project from crank-shaft Gr, through the medium of bell-crank O and bent rod P. The opposite end of the screen (being that most remote from fan) is entirely open, and is attached by rod Q to retracting-spring-R. That portion T of the top of the spout to which the hopper J is attached is removable, and is secured in place by means of bolts U passing through ears V that project from the spout. The removability of the hopper J and its base T enables the inspection and temporary removal or substitution of different grades ot' screens or riddles. A slide, W, enables the adjustment of the passage ot' the hopper. That portion of the spout-floor beyond the hole S is a sliding piece, X. A register, Y, pivoted underneath the drum, enables the regulation of the blast by contraction or expansion ofthe inlet Z.

Operation.

Uncleaned grain being fed into hopper J descends through oriee K into the screen L. in which passage-encountering the blast in flank-the chaffl is thereby driven out through the open spout B. The cheat and other small refuse, too heavy for removal by the blast, drop through the screen and out through hole S in the spout-bottom, While the good grain, being carried slowly forward, escapes into the adjustable lioor of the spout at X.

I claim as new and of my invention- The described arrangement of blast A B O D Z, hopper J K NV, screen L M M', and adj ustable door X with the described agitating and regulating devices, as and for the purpose explained.

' In testimony of which invention I hereunto set my hand.
